The Selection Committee of the Breakthrough Prize in Fundamental Physics today announced a Special Breakthrough Prize in Fundamental Physics recognizing British astrophysicist Jocelyn Bell Burnell (an honorary AAS member) for her discovery of pulsars — a detection first announced in February 1968 — and her inspiring scientific leadership over the last five decades.

Bell Burnell receives the Prize “for fundamental contributions to the discovery of pulsars, and a lifetime of inspiring leadership in the scientific community.” The discovery of pulsars was one of the biggest surprises in the history of astronomy, transforming neutron stars from science fiction to reality in a most dramatic way. Among many later consequences, it led to several powerful tests of Einstein’s theory of relativity, and to a new understanding of the origin of the heavy elements in the universe.

Yuri Milner, one of the founders of the Breakthrough Prizes, said, “Professor Bell Burnell thoroughly deserves this recognition. Her curiosity, diligent observations and rigorous analysis revealed some of the most interesting and mysterious objects in the universe.”

The Special Breakthrough Prize in Fundamental Physics can be awarded at any time in recognition of an extraordinary scientific achievement. This is the fourth Special Prize awarded: previous winners are Stephen Hawking, seven CERN scientists whose leadership led to the discovery of the Higgs boson, and the entire LIGO collaboration that detected gravitational waves.

Five decades after her dramatic discovery of the pulsar, Bell Burnell will be recognized at the Breakthrough Prize ceremony on Sunday, 4 November 2018.

Discovery of Pulsars

Jocelyn Bell Burnell was a graduate student in the mid-1960s, working with Antony Hewish at the University of Cambridge. While taking data with a new radio telescope that she had helped build, she found an unexpected signal: regular pulses of radio waves. With perceptiveness and persistence she characterized the signal and showed it originated from space. She had discovered pulsars. Hewish shared with Sir Martin Ryle the 1974 Nobel Prize in Physics “for his decisive role in the discovery of pulsars.”

“Jocelyn Bell Burnell’s discovery of pulsars will always stand as one of the great surprises in the history of astronomy,” said Edward Witten, the chair of the Selection Committee. “Until that moment, no one had any real idea how neutron stars could be observed, if indeed they existed. Suddenly it turned out that nature has provided an incredibly precise way to observe these objects, something that has led to many later advances.”

The study of pulsars has led to some of the most stringent tests of the general theory of relativity and the first observational evidence for gravitational waves. In one of the most exciting recent astronomical events, the coalescence of two neutron stars was observed in gravitational waves by LIGO, and in a wide spectrum of electromagnetic waves by a host of other observatories. Such coalescences — called kilonovae — are among the primary sources of heavy elements, like gold, that are so much a part of our daily lives.

A Lifetime of Leadership

For the last half-century, Bell Burnell has remained deeply engaged in astronomy, teaching at multiple research institutes and taking on leadership roles such as project manager of the James Clerk Maxwell Telescope in Hawaii. Ever a champion of science, education and the STEM curriculum, she has been President of the Royal Astronomical Society, and the first female President of both the Institute of Physics and the Royal Society of Edinburgh. Bell Burnell is currently a Visiting Professor of Astrophysics at the University of Oxford, and Chancellor of the University of Dundee. She received a CBE in 1999 and a DBE in 2007 for her services to astronomy.

Special Breakthrough Prize in Fundamental Physics

A Special Breakthrough Prize in Fundamental Physics can be awarded by the Selection Committee at any time, and in addition to the regular Breakthrough Prize awarded through the ordinary annual nomination process. Unlike the annual Breakthrough Prize in Fundamental Physics, the Special Prize is not limited to recent discoveries.
